SPECIFICATION forming part of Letters Patent No. 380,091, dated March 27, 1888.

Application tiled May 23, 1887.

Serial No. 239,061. (No model.)

To all whom, t may concern:

Beit known that I, GEORGE D. GoREY, a citizen of the United States, residing' at Lowell, in the county of Middlesex and State of Massachusetts, have invented new and useful Im provements in Jars or Bottles for Fruit, Milk, &c., of which the following is a specilication.

My invention relates more particularly to jars or bottles of glass or other similar material, and especially to the cover thereof and means for holding said coverin place.

My invention is illustrated in the accompanying drawings, in which similar letters of reference refer to similar parts, and in which- Figure 1 is a view in perspective of a portion of a fruit or milk jar, its cover-clamp, and its cover. Fig. 2 is a central vertical sectionof the same, and Fig. 3 is a view of the bail or cover-clamp removed from the jar.

A represents the body of the jar, which is provided near its mouth with the annular ledge Vc, constituting the support for the rubber or equivalent sealing-band b. A portion, A', of the` jar A, near the mouth thereof and below the ledge a, is made in the shape of the frustum of a cone, with its larger base uppermost, and is made in this shape in 'order that the clamp which holds the cover in place may engage with this frustum in whatever angular position the cover B may be placed upon the band b. The cover B is provided with the lower sealing-rim, B', which rests upon the sealing-band b, and is preferably provided with the upper rim, B,

which is elevated above the main body of the cover, and is intended to serve as a surface upon which the jar may securely rest when inverted for storage purposes. This inversion of the jar has been found to be desirable with older forms of jars sealed byrubber bands, since in such cases the contents of the jars have, after long periods, been found to be preserved in better condition than the contents of those filled at the same time with similar substances and which were not inverted for storage.

`In order thatthe jars may stand securely,

when inverted as described, and in order that the cover-clamp may be properly held in position, the diametrically-opposed grooves C are usually made through the rim B and preferably fully as deep as the diameter of the wire the grooves Gare preferably made,as shown in Figs. y1 and 2,to form an extensive surface for contactwith the cover-clamp. Thisl extensive surface is desirable, because the material of the cover will in that case be less likely than otherwise to have its surface broken.

down upon the sealing-baud bis provided with the horizontal bars D, which may be joined as shown in'Fig. .1, or in any other convenient and desirable way, or which may terminate at or near the inner edge of the upper rim, B". -In case the barsD do not form one continuous bar, as shown. in Fig. 1, a wire of larger diameter must be' necessarily employed from which to make the cover-clamp than would be otherwise necessary.

' Joined to the horizontal parts D are the elastic arms D', which are shown as being subf project beyond the jar unnecessarily, and to these arms D are joined the inwardly-projecting portions D'l thereof', which press iirmly against the frustum A with an elastic pressure when the clamp is in its operative position,

elastic stop-bar D. placing the cover B upon the sealing-ring b, that rests upon the ledge a; of the jar A, and then placing the cover-clamp in place in the grooves C with the portions Dl nearly horizon'- tal. The clamp is then rotated in the grooves C and until the stopbar D, which moves downwardly during this rotation, strikes'the body of the jar. When this occurs, the portions D have just passed the perpendicular .position on account of the dimensions of the parts of the clamp, and -for the same reasony they are also pressing with an elastic and firm pressure against the sides of the frustum A.

the cover-clamp is in the locking position shown in Fig. 1, the portions D` pressing tinuous elastic pressure. To open the jar, it is which forms the cover-clamp. The bottom of.

as shownin Fig. 2. The inwardly-projecting. portions D are usually joined by the curved rlhis jar is sealedy by.

The angle of this frustum is so made that whenk against the sides of said frustum, the cover By will be held to the mouth of the j arrwith a con- The cover-clamp which holds the cover A o lstantially vertical, in order that they may not only necessary to relieve this elastic pressure by raising the stop-bar D", after which the cover may be readily removed in the usual manner.

What I claim as new, and desire to secure by Letters Patent. isn l. Thejar provided with a conical 'rustuiu having its larger base uppermost near its mouth and a sealingband-supporting ledge between said larger base and said mouth, combined with a sealing-band resting on said ledge, a cover with a downwardly-extending sealingrim resting on said sealing-band, and a coverclamp resting en said cover and provided with downwardly and inwardly projecting arms pressing with an elastic pressure inwardly on the sides of said frustuui, and a stop to hold said cover-clamp in itslloeking position, substantially as describedfand for the purposes specified.

2. The jar provided with a conical frustum having its larger base uppermost near its mouth and a sealing-bandsupporting ledge between said larger base and said mouth, combined an elastic pressure on the sides of said frustum,

and the elastic curved stop-bar connecting said 3 5 downwardly-extending arms, substantially as described, and for the purposes specified.
